[Libreoffice] --enable-dbgutil now with STL debugging

[Michael Stahl]

hi all,

[sorry for the late mail, but i didn't realize i had accidentally pushed 
this last week (is there an equivalent of "hg outgoing" for git?).]

with commit e0c72547ce57c25db61ec3da6c2f2f2792348c7d the debug mode of 
libstdc++ is now enabled on all platforms that use the unxgcc makefiles 
(guess that is all GCC using platforms except MacOSX and MinGW).

this is only active if you configure with --enable-dbgutil.

because the libstdc++ debug mode is not binary compatible with the 
non-debug mode, mixing of object files with it enabled/disabled will 
probably lead to hard to debug crashes, so: if you have a build with 
--enable-dbgutil on affected platform, then please _remove_ all output 
directories (make clean) and build _from_scratch_.

oh, and if you do not build with --enable-dbgutil: why not ?
it will help you find problems...

if you find problems even in a build from scratch please let me know, it 
seems to work fine here :)

if somebody wants this on MacOSX or MinGW as well, please try it out and 
enable it if it works; i can't test those platforms and they are 
sufficiently different that i won't enable it now.

regards,
  michael
